This might seem strange, but I took my 1-year-old iSonic 105 out for the first time with a 6.6 (and stock 34cm fin). I&#39;ve used it with my 4.8, 5.6, 6.0 and an 8.0, but never my 6.6. I think this might be a sweet spot for me on this board. The winds were light for a 6.6, but I still seemed to plane as early as (heavier) people using 140-150L boards and ~8m2 sails. One guy had a 9.5m2 rigged! My usual sailing buddy who I gauge my speed against is usually a little faster than me. This time, he was a little slower. No matter what he did, I was faster. Usually he uses 1m2 larger sails than me. This time, the gap was even bigger than that, but still I was able to gain on him. He commented afterwards that my iS105 was coasting through lulls better than his 150L board.

I&#39;m also in love with winter sailing (when the temperatures are warm enough). It was warm enough the other day that I didn&#39;t need a drysuit or steamer. I wore a 3/2 wetsuit and booties. The best part though was the simple fact that there were no boats making waves. We had very little fetch, so the lake was smoother than I&#39;ve ever seen it. When the winds filled in to power the 6.6 up completely, the iS105 started to float. I&#39;ve had fun on this board before, but never this much fun.

For winter days like the above, I kept an old 120L 73cm wide AHD. It is super stable and great to use if you want to stay dry. In 2 hours of sailing on the iS105 (doing duck jibes, etc.), I only fell in once (couldn&#39;t unhook when the wind shifted). So, now I&#39;m thinking I&#39;ll get rid of that old board. I can easily go from my iS105 to my F-Type 148 in any season.
